Orange ball of light floats across the night sky

Myself and another witness were outdoors celebrating the new year when we observed a single bright orange ball of light travel across the night sky. It stayed on a northerly track, did not change altitude, and took about 20 seconds to cross the horizon until it was out of view. Fireworks were being set off at the time, but this did not appear to be any kind of firework, chinese lantern, or paper on fire. It was too bright, fast, and tracked steadily. The sky was slightly foggy, but the ball of light was very visible. There was no sound.
Interestingly, this is my second report of this nature. The last one was in New Caney, TX on the night of July 4, 2012. There were also fireworks being set off that night, but without the fog I could clearly see it was a ball of what looked like fire. This was a nearly identical sighting in duration and way it behaved.
Also, upon talking to one of my neighbors since then, he also witnessed the one in 2012, although I did not know at the time of my report, so I did not include this information.
